Total Time: It took about 20 minutes for this experiment to go to completion
Difficulty: Supervision is suggested when the kiddos are handling the essential oils, just to make sure they don't get it in their eyes or pour half the bottle onto the styrofoam. Overall, a very simple experiment though.
Materials You Need:
Permanent markers (if drawing faces on the cups)
Citrus essential oils (we used Lemon, Lime, Orange, and Citrus Bliss, but feel free to use any citrus oils you have on hand)
- Draw a spooky face on an upside-down cup.
- Carefully drip 1-2 drops of essential oil onto the cup.
- Wait a few minutes and watch it eat a hole right through the brains of your cup guy!
